list_browser->tab

list_browser ->tab_stops: vector*

Set a number of tabulator stops. The argument is a vector with pixel locations of the tab stops. See also text_image->tab_stops.

This feature may be used for multi-column tables and is especially useful when the items in the browser are displayed in a proportional font. The following example displays a database of persons where each person has a unique id and a name. The database is in the predicate person/2.

?- new(B, browser('Persons')),
   send(B, tab_stops, vector(200)),
   forall(person(Id, Name),
                  send(B, append,
                           dict_item(Id, string('%s\t%s',
                                                                        Id, Name)))),
   send(B, open).
